"Yes, 1850 was during the Little Ice Age." It was the end. It also was after the Industrial Revolution was taking off, the burning of fossil fuels started to take off and CO2 levels started to increase after being more or less stable for a very long time. "I would certainly hope that there would be an upward trend from the Little Ice Age, back to "normal" rather to a full fledged Ice Age..." The trend had been down since the peak some 15k years ago. If the Medieval Warm Period was actually global and not local, then that would have represented an outlier. But, until the recent warming, the temperature profile looked remarkably like the earlier ones leading to glaciation. "If you cherry pick your starting and ending point, you can come up with any conclusion you want." It isn't cherry picked. There are solid reasons to take the 1850s as a starting point. That is when we started to exploit fossil fuels and that is when the CO2 levels started to climb.
